Monodie (French for 'Monody') is the shortest stand-alone published composition for organ by French composer Olivier Messiaen.

The Monodie was composed in 1963 at the request of Jean Bonfils, who was Messiaen's assistant at the church of the Sainte Trinité, Paris, where he was the main organist. It was written for Bonfils's and Noémie Pierrot's organ method book entitled Nouvelle méthode de clavier. Messiaen presumably did not have his own organ at La Trinité because of a major refurbishment.^[1] It was then published as a part of that book in 1963 by the Schola Cantorum. Musicologist Nigel Simeone alleges that Messiaen could have composed the Monodie as a part of a sight-reading examination at the Schola Cantorum.^[2] The piece was later republished posthumously by Éditions Alphonse Leduc in 1997, as most other short works that were lost, forgotten, or never intended for publication.^[1] It was formally premiered on May 19, 1998, at Westminster Cathedral, in London, with Gillian Weir at the organ.^[3]

This composition has a total duration of 6 minutes and a total of 17 bars of variable length. As was customary in many works by Messiaen, the monodie has no time or key signature. It starts with a single staff (as opposed to a three-staff system, which is typical of organ works). Messiaen used the tempo marking "Très modéré". The stop configuration used in the piece is stable throughout: Flute 8 (or Quintaton 16), Cor de Nuit 8, Nazard 2⅔, and Octavin 2. The piece features multiple triplets, quintuplets and sextuplets.^[4]
